Tardive dyskinesia, an often irreversible adverse effect that usually results from chronic use antipsychotic medications, especially the high-potency first-generation antipsychotics. It is characterised by slow (hence tardive), involuntary, repetitive, purposeless muscle movements.
Blood dyscrasias e.g. agranulocytosis (a potentially fatal drop in white blood cell count), leukopaenia (a drop in white blood cell counts but not to as extreme an extent as agranulocytosis), neutropaenia (a drop in neutrophil [the cells of the immune system that specifically destroy bacteria] count), thrombocytopaenia (a dangerous drop in platelet [a cell found in the blood that plays a crucial role in the blood clotting process] counts), purpura (the appearance of red or purple discolourations of the skin that do not blanch when pressure is applied), eosinophilia (raised eosinophil [the cells of the immune system that specifically fights off parasites] count)
Hepatitis — inflammation of the liver
Oedema — the abnormal buildup of fluids in the tissues
Peripheral neuropathy — nerve damage
Numbness, tingling and paresthesias of the extremities
(Binding) As above. This action is believed to be partly responsible for the lower
EPS liability of newer antipsychotics and also responsible for their higher weight
gain liability compared to most typical antipsychotics.
